Obama Warns Syria's Assad Chemical Weapons A 'RED Line'

President Obama made a surprise appearance during Jay Carney's White House briefing. Speaking to a packed press room, he raised a smile as he traded banter with them before launching into the serious issue of Syria and chemical weapons.

He confirmed that the US has said Assad needs to step down.

Obama then tackled the issue of humanitarian aid to Syrians, and those who are fleeing the country to escape the Assad regime ,severely straining the resources of nearby host countries.

And the President ended the briefing on a serious note, by saying that should the US and United Nations be aware of any chemical weapons then they would react accordingly to the threat.

On the same day that Obama made this statement in the US, the Russian Minister and Syrian ally, SERGEI LAVROV speaking at a news conference in Helsinki, said Moscow would not approve any political transition that was forced on Syria. Stating that only the United Nations Security Council alone, can authorise the use of force against Syria, and not just the US.
